Question: Is the JDBC-ODBC Bridge multi-threaded?
Answer: No. The JDBC-ODBC Bridge does not support concurrent access from different threads. The JDBC-ODBC Bridge uses synchronized methods to serialize all of the calls that it makes to ODBC. Multi-threaded Java programs may use the Bridge, but they won't get the advantages of multi-threading. In addition, deadlocks can occur between locks held in the database and the semaphore used by the Bridge. We are thinking about removing the synchronized methods in the future. They were added originally to make things simple for folks writing Java programs that use a single-threaded ODBC driver.

Hope above question will help you.

Thanks

No. The JDBC-ODBC Bridge does not support concurrent access
from different threads. The JDBC-ODBC Bridge uses
synchronized methods to serialize all of the calls that it
makes to ODBC. Multi-threaded Java programs may use the
Bridge, but they won?t get the advantages of multi-threading.
